An example of the element Tellurium

Tiny crystal.
This is a small chip from a small bag of tellurium crystals I received from Oliver Sacks on a visit. I used it to test my very small turntable, constructed to allow accurate rotation of samples down to a couple of mm in size.Source:Oliver SacksContributor:Oliver SacksAcquired:4 August, 2004Price: DonatedSize: 0.1"Purity: 99.9%
